* Checks the list of stats keys returned from the HTTP endpoint
is complete -- delineating between riak and riak_ee. The test will
fail if the list returned from the HTTP endpoint does not exactly match
the expected list. This behavior acts as a forcing function to ensure
that the expected list is properly maintained as stats are added and
removed.
* Modifies reset-current-env to properly clean dependencies when a
full clean is requested and remove the current directory in the
target test instance.
* Adds logging to verify_riak_stats to explain the addition steps
being performed
* Adds rt:product/1 to determine whether a node is running riak,
riak_ee, or riak_cs
* Adds tools.mk support and eunit scaffolding to rebar.config
* Modifies reset-current-env.sh to remove the current directory in
the target test instance
